Hi. Greetings. Stretch marks may not be "cured". However their appearance may be improved by application of substances like bio oil, topical retinoid creams, fractional laser therapy/ micro needling/ micro needling rf. The efficacy of procedure and amount of improvement is variable. Discuss the same with your dermatologist. There's no magic that can be done in ten days. You can use a concealer instead. Hope this helps. Warm regards. Dr Govind Suresh Mittal.
